CORN-PLANTER.

SPECFICATIO forming part of Letters Patent No. 345,757, dated July 20, 1886.

Application filed March 30, 1886.

To all whom t may concern;

Be it known that we, JOHN MOSES ALLIsoN and CHARLES PRATTSMAN BOWDEN, citizens of the United States, residing at Columbia and Johnstown, in the counties of Boone and Bates and State of Missouri, have invented a new and useful Improvement in Corn-Plant ers, of which the following is a specification, reference being had to the accompanying drawings.

Our invention relates to improvements in corn-planters, having for its object the provision of an implement of the class named, the several parts of which are simple, durable,

and easily operated.

Vith this end in view the invention consists in the construction, arrangement, and combination'of parts, substantially as hereinafter described, and specifically pointed out in the claims.

Referring to the drawings, in which similar letters of reference denote similar parts, Figure l represents a top plan view of a corn-planter embodying` our improvements. Fig. 2 is a side elevation thereof. Fig. 3 is a transverse sec tion on the line x :c of Fig. 2. Fig. 4 is a detail perspective view of the lever .that operates to raise and lower the drill-opening shoes. Fig. 5 is a detail vertical sectional view on the line y y of Fig. 1.

In the drawings, A designates the frame of the machine, which is in two parts, A A2, hinged together at b. Theformer of said parts, A', consists of side rails a and intermediate 5 rails o a2, held in position by transverse rails o3 at. The intermediate rails a/ cL are placed a short distance from each other, in planes parallel with the side rails a, to form a space, ai, in which operates one of the wheels of the 40 planter, as hereinafter described.

a designates transverse timbers that extend from the outer surfaces of the rails a a? to the side rails c at each side of the machine, for the purpose of supporting an axle, c, placed in juxtaposition with the lower surfaces 'of said timbers a, and upon which the wheels D DYDL of the machine are mounted.

E designates a seat mounted upon the rear end of a seatsupporting spring, E', that extends from the rail a3.

e designates nprights that extend from the Y lower surface ofthe scat to the bars or rails a a2. F designates a bell-crank lever fulcrnmed at f to a short timber, f, extending between the rails a3 a, at the right-hand side of the ma- 55 chine, within reach of the drivers seat. The upper end or arm of the lever F is provided with a spring-controlled rod, f, the lower end of which engages with detente formed in a rack-segment, f4, securedV to the frame A.

f5 designates the handle that operates the rod]2 up or down. The lowerarin ofthe lever F extends forward to a point below the transverse rail a3, thence laterally to a point below the forward end of the rail a, thence forward below the rear end of the timber b3 ofthe part A2, and is received in a staple or loop projecting downward from said timber at the point last named'. The end of the lever-arm is bent downward, for a purpose to be explained fur- 7o ther on. The forward frame-section, A2, consists of side rails b and intermediate spaced rails bt b, held in position by transvers rails b4 b5. v

b bl designate short rails secured tothe outer 7 5 ends of the rails b* b5, outside of the side rails b, to form bearings for short seed-plates h, that extend from one to the other of the timbers b b5 and b' bl, as well as the intermediate timbers bZ b3 in rear of the transverse 8o rail b5, and also for the purpose of forming balgs for the hoppers G, hereinafter described B designates the draft-pole or tongue, secured at its rear end between t-he timbers b2 85 Zi of the part A2, and extending thence forlward over the rail bt. I

bs bJ designate braces extending diagonally in the spaces formed by the side, end, and intermediate rails of said part A2, as shown.

G designates the hoppers, preferably three vin number, consisting of inclined sides and ends g gand hinged covers g2. The hoppers G are placed in position over the seed-plates h, and are provided at their ends, near the v bottoms thereof, with cnt-away parts, through which the feed-bar Hoperates. The feed-bar consists of a flat plate of metal, having apertures 7i formed therethrough at distances similar to the distance between the apertures of IOO the seedplates, and said bar is placed and moves upon said seed-plates, the apertures h therein registering with the apertures in said seed-plates, to permit the passage of seed from the hopper to spouts z', secured yto the rear sides ofthe downwardly-projecting shoe, supporting studs I, secured to the lower surface of the rail b5.

I2 designates an oscillating bar pivoted at its middle to the studs I in the spouts z'.

I designates the drill-opening shoes, the forward ends o1" which are secured to the transverse rail b, and from thence extend down ina curved plane to the lower end of the studs I, at which points they are provided with bifnrcated portions, through which the seed drops to and into the drill.

The seed-bar H is operated by a bell crank lever, K, having a bifurcated forward end, that engages a pin, ILS, projecting upwardly from the bar H. SaidleverKis fulcrnmed upon the rearwardly-projecting end of the timber b, and is connected by a rod1 7c, with a crankpin, c, projecting from the wheel D.

By reference to the drawings it will be ohserved that the parts A A2 of the frame may be set and held at angles with each other by the lever F, for the purpose of causing the shoes I to open deep or shallow drills, as de sired.

Modications in detail of construction may be made in the herein-described invention without departing` from the spirit or sacriiicing the advantages thereof.

It will be observed from the foregoing description, taken in connection with the drawings, that the section A of the-frame is carried by the axle c and the bearing-wheels, which are jonrnaled thereon, and also the seat and lever for elevating or depressing the frame-section A2, which is hinged to and carried by the section A. The frame-section A2 can be conveniently and easily elevated or depressed by the operator seated on the section A, and the seed-tubes and dropping or planting devices are also carried by the section A2, and can be adjusted therewith without interfering with the operation of planting. The swinging bar I2 serves to prevent the passage of seed from the hopper to the cond noting-tube at the end of each stroke of the reciprocating slidebar H, and the upper end of the said swinging bar or valve projects through the slot of the hopper-bottom h, and into the slot of the slide-bar, so that the valve is swung on its pivot from one side to the other, and the lower end of the valve or rod is caused to bear against or come in contact with opposite sides ofthe seed-tube alternately, as will be very readily understood. The hand-lever F is pivoted or fulcrumed on the frame-section A', and it has a right-angled arm, m, that lies in line therewith and extends to the front rail, a3. The free end of thearm ia is bent at right angles to provide the arm a, that lies out of line with lever F, the' free end of the said arm a being bent to provide the end o, that lies parallel with and to one side of the arm m, and engages the staple or loop on the frame-section A2, to elevate the latter. By the peculiar arrangement and disposition of the arms 'in n o the direct weight and strain of t-he frame-section A2 on the pivot or fulcrum of the lever E is reduced,and the parts are rendered more durable, from the fact that the pivotis not so liable to be broken.

Having thus described our invention, we claiml. In a corn planter, the combination ofthe frame-section A, carrying the supportingwheels, the axle therefor, and the drivers seat, the frame-section A2, hinged directly to the section A at b, and carrying the seed-hoppers, the reciprocating slide-bar, and the conducting tubes, the level F, fulcruined upon the section A in juxtaposition to the seat thereon, and having the arms m u o, arranged as described and connected to the section A2, for elevating or depressing the latter, and lever and pitinan connections intermediate of one ofthesupporting-\vheels,andthe reciprocating bar for actuating the latter, as set forth.

2. In a corn-planter, a twopart-frame, A, hinged together at b, one of its parts, A', having wheels D D D2, mounted upon an aXle-rod, seat E, spring E, lever F, and rack -segment ft, in combination with the part A2,

.having drill-opening shoes I, studs I, and

spouts t', having an oscillating` bar, I2, hoppers G, having seed-bark, provided with openings, feed-bars H, operated by a bell-crank lever,

K, connected by rod k with the crank-pin 7c of 10o the wheel D, substantially as described.

In testimony that we claim the foregoing as our own we have hereto affixed our signatures in presence of two witnesses.
